Hi guys,
I need some help replacing my bottom bracket since it's making clicking noises under load.
Can't seem to figure out what kind of bottom bracket this is. It looks like a square taper BB to me but it also has external cups which is really confusing.
Bike is a Qicycle C2 E-bike. Motor is in the rear hub so shouldn't be anything else in the BB area. Can't find any more info about it online.
Appreciate any input.

The only certain way is to take it out, bring it to a bike shop and ask for a replacement.
Yeah that’s some weird shit you’ll get with off brand bikes. Chances are shops and their distributors may not have replacements but AliExpress does. You will need a width spec on the square taper spindle to get the correct one.
My old shop got some super cheap fat bikes back in the day with square taper BBs that none of our distributors stocked until years later.
